We want AoA. We were told we had it. Our next step is to look through the airplane build logs and other documents to see what we can find in them. I can assure everyone that nothing is located on the under surface of the leading edge that would serve as a pressure port for an AoA system, I also do not see the combination pitot and AoA port that Dynon sells for other installations. So I am clearly missing something about this particular airplane.

FYI, the set up menus for the Skyview with ver 15.2 software include an option for choosing YES or NO for audio AoA wranings and for now I have set that to NO. It was set to YES.

More than likely, your AOA port (IF you have one) is not a big probe but rather a single pop rivet head located near the stall warning tab under the left wing's leading edge.

Sorry, didnt pick up on the fact this is a Skyview. David is right. That makes it a lot harder to get at the end of the tubing, if indeed it is there.

Is it possible to contact the original builder and just ask about the AOA?

If not, how about pulling the wing pins and sliding the wing(s) out a few inches to see if there is tubing?

Basically I agree with Tony. Shut off the distracting noise and figure it out at the next condition inspection. AOA really not necessary in this little airplane, unless you are dragging it into very short strips on a regular basi. JMHO.

Remove the inspection cover located near the stall warn vane under the left wing. Look or feel in there to find the small diameter plastic tube connected to a rivet. The rivet is likely the same as those used for the static ports on the sides of the fuselage.
If the AOA is installed but is not working properly, then the most likely cause is that the Dynon needs to be calibrated and setup.
